摘要: 目的：探讨高频彩色多普勒超声在鉴别乳腺癌腋窝转移性淋巴结与腋窝良性淋巴结中的临床应用价值。方法采用高频二维超声结合彩色多普勒血流显像技术（CDFI）回顾性分析78例乳腺癌患者的腋窝肿大淋巴结共106枚，对比分析56枚乳腺癌腋窝转移性肿大淋巴结与50枚腋窝良性肿大淋巴结的声像图及血流情况。结果乳腺癌腋窝转移性肿大淋巴结与腋窝良性肿大淋巴结在L/S、皮质增厚特点、是否融合、是否钙化、血流信号分布特点及血流丰富程度方面比较，差异均有统计学意义。结论乳腺癌腋窝转移性肿大淋巴结在形态、内部回声、血流分布特点等方面与腋窝良性肿大淋巴结有较明显的区别，高频彩色多普勒超声在鉴别乳腺癌腋窝转移性肿大淋巴结与良性肿大淋巴结中具有较高的临床应用价值。Abstract: Objective To explore the clinical value of high-frequency color Doppler ultra-sonography in identifying axillary metastatic and benignant lymph nodes of breast cancer.Methods 106 axillary enlarged lymph nodes of 78 patient with breast cancer were retrospectively analyzed by high-frequency two-dimensional ultrasonography combined with color Doppler flow imaging (CD-FI).The sonograms and characteristics of blood flow were compared between 56 axillary metastatic enlarged lymph nodes and 50 axillary benignant enlarged lymph nodes.Results There were signifi-cant differences of L /S,thickness-increased characteristics of skin texture,presence or absence of confluent shape and calcified plaque,distribution characteristics of blood flow signals and degrees of blood flow between axillary metastatic and benignant enlarged lymph nodes of breast cancer.Conclu-sion Axillary metastatic enlarged lymph nodes of breast cancer are greatly different from axillary benignant enlarged lymph nodes in the shape,internal echo and blood flow patterns.High-frequen-cy color Doppler ultrasonography is a useful method with higher clinical application value for identi-fying axillary metastatic and benignant enlarged lymph nodes of breast cancer.
